Application filed m 29, 1925. Serial No.125,645.

This invention relates to tools, particularly to wrenches, and has for its object the provision of a novel reversible ratchet wrench in con unct1on with which maybe employedbit elements of various types such as socket wrenches of any s1ze, screw dr1v-' ers or the like, the intentionbeing to PTO", vide a sufficient number of bit elements that work of vdifferent kinds maybe done on orabout machinery or the like;

An important object of may be so constructed that by its use access may be had to parts which areordinarily hard to reach or; impossible to reach by means of the usualmonkey'wrench, open thefllne 88 ofFigurfel,

end wrench or the like. 1

A very important object of the invention. is to provide a ratchet wrenchwhich 1s re; versibl-e and which embodies a pair of selectively usable pawls cooperating with a ratchet for effecting turning movement of Whatever tool or bit is used, novel. means.

being provided forv holding a selected one of the pawls inoperative or outlof engagement with the 'ratchet,'depending upon the desired direction of rotation;

A further object is the provision of a thereby for holding a bit or-other tool" member positively against displacement .or

. showing a socket wrench bit member ;car-' ried thereby,

dropping out, this retaining means being of such nature as to obviate ,anynecessity for the employment of an elaborate chuck:

mechanism.

' An additional [object of'the invention is to providea device of this character which; will be simple :and inexpensive in manufac- ,ture, easy to adjust and operate, rapid ,1n

action, efl'icient in use, durable inservice, and a general improvement in the art. I

With the above and other objects; and advantages in view, the invention preferably consists in the arrangement and combination of parts and detailed structural fea-' turesto be hereinaftermore fully described and claimed, and illustratedein' the accom-' panying drawings in whichaj' Figure 1 is'a sideielev'ation of thewrench Figure 2 is an elevation of a screw .driver which may be used-instead? of the wrench bit or member,

v I the invention is I to provide a wrench of this character which I Figure8 is anelevation of a'lenglthening' bar which may be interposedbetween the wrench and any; of the bit members used i 'in connection therewith,

gaged therein,

The head; is formed in its sides Wltll grooves or recesses 19zwhich extend from o substantially the earsf 18 and which lead into an opening 20 extending entirely -throughthe head as clearly shown .in Figure 8. The provision of the opening 20 actually at opposite ends of the opening, the-former being provided with a hole 23 and the latter with =a;ho1e 24 of largerdiameter. 1
